ROUX-EN-Y GASTRIC BYPASS CHRONIC COMPLICATIONS

Course overview

BARIATRIC SURGERY FOR WEIGHT LOSS HAS BECOME A COMMON PRACTICE. THE SECOND MOST COMMON BARIATRIC PROCEDURE DONE TODAY IS THE ROUX-EN-Y GASTRIC BYPASS (RYGB). TO BE A PRACTICING HEALTH PROFESSIONAL IN THE MODERN ERA, ONE MUST RECOGNIZE THE MORE COMMON CHRONIC COMPLICATIONS THAT MAY RESULT FROM ALTERING THE GASTROINTESTINAL (GI) TRACT AND HOW TO MANAGE THESE COMPLICATIONS. TO DEVELOP KNOWLEDGE REGARDING THE POTENTIAL SEQUELA OF THE OPERATION, ONE MUST HAVE KNOWLEDGE OF THE ANATOMY OF THE GI TRACT AND THE RESULTING PHYSIOLOGIC EFFECTS OF ALTERING THAT ANATOMY. ROUX-EN-Y GASTRIC BYPASS INVOLVES CREATING A SMALL GASTRIC POUCH (RESTRICTING FOOD INTAKE) CONNECTED TO A ROUX LIMB (TYPICALLY BETWEEN 75 TO 150 CM) WHICH BYPASSES A LARGE PORTION OF THE SMALL INTESTINE (PREVENTING ABSORPTION OF NUTRIENTS.) THIS RESULTS IN THE FOOD BOLUS BYPASSING THE MAJORITY OF THE STOMACH (BYPASSES THE PART OF THE STOMACH CONTAINING MOST OF THE PARIETAL CELLS AND STOMACH ACID), THE DUODENUM, AND THE FIRST 40 TO 50 CM OF JEJUNUM. NUTRIENTS WILL ONLY BE ABSORBED DISTAL TO THESE BYPASSED SEGMENTS, AND THE MAJORITY WILL BE ABSORBED IN THE "COMMON CHANNEL" WHICH IS DISTAL TO THE WHERE THE BILIOPANCREATIC AND THE ROUX LIMB CONNECT. THIS ACTIVITY REVIEWS THE COMMON CHRONIC COMPLICATIONS FOLLOWING AN RYGB WITH RESPECT TO EPIDEMIOLOGY, PRESENTATION, DIAGNOSIS, AND TREATMENT AND HIGHLIGHTS THE ROLE OF THE INTERPROFESSIONAL TEAM IN EVALUATING AND TREATING PATIENTS WITH THIS CONDITION.
